Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connection spring, connector and electronic device. Background Technology

[0002] With the advancement of technology and economic development, electronic devices such as mobile phones and tablets have become indispensable daily necessities. These digital electronic products have been widely integrated into people's daily lives, providing great convenience for people's lives and work and enriching their lives. Springs are one of the essential components in electronic devices.

[0003] Each connector in an electronic device has several spring contacts, which are used to connect the circuitry or devices on both sides of the spring contacts. With the trend of miniaturization in electronic devices in recent years, the connectors inside the devices have also become smaller. The existing application of spring contacts is to place the spring contact connector on one side of the substrate, and the other substrate is provided with a contact surface that contacts the spring contact to achieve the purpose of crimp connection.

[0004] However, existing spring contacts have a relatively large height due to the significant drop between the contact point and the top suction section (used for material suction during operation), which limits their application scenarios and makes them unsuitable for the trend of miniaturization in electronic devices. Furthermore, the existing spring contacts have a discontinuous support design on both sides, making them prone to breaking apart upon impact, thus affecting product functionality. Utility Model Content

[0005] One objective of this invention is to provide an electrically connected spring to solve the problem in the prior art where the product is relatively tall and easily blown apart upon impact.

[0006] An electrically connected spring includes an integrally formed suction portion, a first support portion, a second support portion, a connecting portion, and an elastic portion. The suction portion extends downward from both ends in a first direction to form the first support portion and the second support portion, respectively. The suction portion extends downward from one end in a second direction to form the connecting portion. The end of the connecting portion away from the suction portion extends to form the elastic portion. A portion of the elastic portion is housed within the space enclosed by the suction portion, the first support portion, the second support portion, and the connecting portion. The elastic portion includes a first elastic arm, a second elastic arm, and an elastic contact portion. An arc-shaped transition portion is provided between the connecting portion and the first elastic arm, and between the first elastic arm and the second elastic arm. The end of the second elastic arm away from the first elastic arm extends downward to form the elastic contact portion.

[0007] According to the electrical connecting spring proposed in this utility model, since the end of the suction part extends downward along the second direction to form a connecting part, and the end of the connecting part away from the suction part extends to form an elastic part, and part of the elastic part is housed in the space enclosed by the suction part, the first support part, the second support part and the connecting part, this structural design can reduce the height difference between the elastic contact part and the suction part, thereby reducing the height of the product and expanding the application scenarios. In addition, since the suction part extends downward along the first direction to form a first support part and a second support part respectively, and the suction part, the first support part and the second support part are integrally formed, the structural strength of the product can be improved, and the risk of the product being blown apart when it is subjected to a collision can be effectively reduced.

[0008] In addition, the electrical connecting spring provided by this utility model may also have the following additional technical features:

[0009] Furthermore, the first support portion extends a first limiting portion toward the second support portion, the second support portion extends a second limiting portion toward the first support portion, and the end of the elastic contact portion away from the second elastic lever arm extends a latching portion. The first limiting portion and the second limiting portion contact the latching portion, thereby limiting the latching portion.

[0010] Furthermore, an arc-shaped transition portion is provided between the buckling portion and the elastic contact portion.

[0011] Furthermore, a third support is provided between the first support and the second support. The first support, the second support, and the third support are integrally formed, and the third support has an integrally formed notch. Welding feet are provided at the bottom of the first support, the bottom of the second support, and the bottom of the third support.

[0012] Furthermore, the elastic contact portion has a U-shaped structure.

[0013] Furthermore, the surface of the elastic contact portion is provided with a contact protrusion.

[0014] Furthermore, the first direction is perpendicular to the second direction.

[0015] Furthermore, the first support portion, the second support portion, and the connecting portion are perpendicular to the suction portion.

[0027] Please see Figures 1 to 4 The first embodiment of this utility model proposes an electrical connecting spring 100, which includes an integrally formed absorption part 10, a first support part 20, a second support part 30, a connecting part 40, and an elastic part 50.

[0028] The suction part 10 extends downward from both ends along the first direction to form the first support part 20 and the second support part 30, respectively, and the suction part 10 extends downward from one end along the second direction to form the connecting part 40.

[0029] Preferably, the first direction and the second direction are perpendicular. The first support portion 20, the second support portion 30, and the connecting portion 40 are respectively perpendicular to the suction portion 10.

[0030] The elastic portion 50 extends from the end of the connecting portion 40 away from the suction portion 10. A portion of the elastic portion 50 is housed within the space enclosed by the suction portion 10, the first support portion 20, the second support portion 30, and the connecting portion 40. The elastic portion 50 includes a first elastic arm 51, a second elastic arm 52, and an elastic contact portion 53. Arc-shaped transition portions are provided between the connecting portion 40 and the first elastic arm 51, and between the first elastic arm 51 and the second elastic arm 52. The elastic contact portion 53 extends downward from the end of the second elastic arm 52 away from the first elastic arm 51. Specifically, the first elastic arm 51 first extends upward at an angle from the end of the connecting portion 40 away from the suction portion 10; the second elastic arm 52 then extends downward at an angle from the end of the first elastic arm 51 away from the connecting portion 40; and finally, the elastic contact portion 53 extends from the end of the second elastic arm 52 away from the end of the first elastic arm 51.

[0031] Preferably, the elastic contact portion 53 has a U-shaped structure. The surface of the elastic contact portion 53 is provided with a contact protrusion 531.

[0032] Since the suction part 10 extends downward from one end along the second direction to form a connecting part 40, and the end of the connecting part 40 away from the suction part 10 extends to form an elastic part 50, and part of the elastic part 50 is housed within the space enclosed by the suction part 10, the first support part 20, the second support part 30 and the connecting part 40, this structural design can reduce the height difference between the elastic contact part 53 and the suction part 10, thereby reducing the height of the product and expanding the application scenarios. In addition, since the suction part 10 extends downward from both ends along the first direction to form the first support part 20 and the second support part 30 respectively, and the suction part 10, the first support part 20 and the second support part 30 are integrally formed, the structural strength of the product can be improved, and the risk of the product being blown apart when it is hit is effectively reduced.

[0033] In this embodiment, the first support portion 20 extends a first limiting portion 21 toward the second support portion 30, the second support portion 30 extends a second limiting portion 31 toward the first support portion 20, and the elastic contact portion 53 extends a latching portion 60 from one end away from the second elastic lever arm 52. The first limiting portion 21 and the second limiting portion 31 contact the latching portion 60 to limit the latching portion 60, thereby further improving the structural strength of the product.

[0034] Preferably, an arc-shaped transition portion is provided between the buckling portion 60 and the elastic contact portion 53.

[0035] In this embodiment, a third support portion 70 is provided between the first support portion 20 and the second support portion 30. The first support portion 20, the second support portion 30, and the third support portion 70 are integrally formed, and the third support portion 70 has an integrally formed notch 71. The bottom of the first support portion 20, the bottom of the second support portion 30, and the bottom of the third support portion 70 are all provided with solder feet 80. Since these solder feet 80 are soldered to the PCB board, the problem of reduced product structural strength caused by the integrally formed notch can be alleviated.
